Figure 1.

ARH is expressed in columnar epithelial cells and pulls down AP-1B. (A) RT-PCR was performed to amplify canine ARH, Rab8, or Rab10. Lane 2 shows a heat inactivation control for ARH amplification. (B) qRT-PCR was performed using one set of primers specific for canine ARH, Rab8, or μ1B. Transcript levels from at least three independent experiments done in triplicate were plotted in relation to a GAPDH control. Error bars indicate SD. (C) MDCK, HBE, and LLC-PK1::μ1B cell lysates were analyzed by SDS-PAGE and Western blotting using anti-ARH antibodies. (D) 3T3 (lanes 1 and 2) or EFA47 (lanes 3 and 4) cell lysates were incubated with purified His-ARH or NiNTA beads alone followed by SDS-PAGE and Western blotting using anti–γ-adaptin (shown are two different exposure times of the same blot) and anti-His antibodies. Lanes 5–8 show input controls for lanes 1–4.
